Why Do Numbers Feel So Familiar?

Imagine you're counting your toys, you say 1, 2, 3, and suddenly one of them feels extra special. That’s number familiarity! It's like when numbers seem to know you, just like old friends. Some people feel this with small numbers, like 10 or 15; others might be drawn to bigger ones, like 99 or 100. Scientists think it happens because our brains learn to recognize patterns in numbers, and some numbers feel more familiar than others, just like certain shapes or sounds.
